Lifestyles, Big Families, and Rotational Gameplay

I experimented with lifestyles for a while, but now it's time to turn them off, because I am so very tired. Everyone keeps getting close-knit, which makes them upset when they interract with their siblings and friends, because now they suddenly have too many friends, what a tragedy, or health-food nut, which makes them hate everything but a small number of foods. My sims are better off without this nonsense.
